are you stock cooling please?
list of guides to follow here,
please read a guide to understand how your bios setting work.
I like this one the most,
if you do understand then its easy as this....Disclaimer
if you follow the advice below, you do so at your own risk and at risk, your personal computer is all your own property and problem, and is not my fault.
if you follow the
below, you do so at your own
is all your own
, and is not
please monitor your temp with hwmonitor and cpu-z for reading clocks,
70c of any cpu temp [cpu or core temp] is max for the FX4xxx and FX6xxx
and 61c of any cpu temp [cpu or core temp] is max for the FX8xxx,
one: go in to bios, hit del at start-up till you get to a blue-grey screen before windows.
two: go to the advanced tab, then go in to cpu configuration and disable cool and quite and everything there on that tab.(c1e,c6 state, hpc and apm (application power management))
three: press esc and go down one to northbridge, go in there and theres one thing to go in to , there you will see ECC enabled, disable that.( happens on asus mobo's)
now for the overclock......
four: got to the ai tuner tab of bios and change it to manual from auto.
five: got to cpu ratio and change to 20 x
six: disable turbo core
seven: go to ref clock and change to 200
eight: change your ram to the right speed, 1600mhz or whatever and set your ram timings.
nine: go to cpu load line calibration and change to high (I use ultra high on my m5a99x evo and on the sabretooth i found it to be medium)
ten: go to cpu voltage change to manual and change that to 1.29v (1.325v is stock).
now got to that last tab in bios save and exit.
you should now boot at 4ghz and be near stable under full load.
download cpu test programs
hyper pi is a memory test program, but it runs cooler than most cpu tests and will usually crash with os still running.
good for instantly knowing if your cpu is nearing stability.
occt is stability test program, will usually crash hardware and software if cpu/system is unstable.
good for long term oc tests.
need to test your cpu load line config with a heavy load ,use hyper pi, watch your voltage and give it a 1m test, what voltage do you get under full load, move you load line up or down for increases or decreases to voltage and make it level under full load
if you go extreme llc, lower voltage of cpu as it will climb a bit under load.
now run a full hour cpu test to see if it's stable, I used occt medium test for 2 hours.
i got a nice 4ghz stable at 1.284v at idle and under full load.
EDIT;this is my copy and paste advice for fx.
I did manage to get six core of the eight up to 4.6ghz with 1.464v showing in cpu-z.
it had heat issues after that, and my mobo is only a 6+2 vrm.Edited by MrPerforations - 1/25/13 at 5:42am
